RBF

RBF

rude slang An abbreviation for "resting bitch face," a perpetually angry or sullen look on one's face when it is "resting" or neutral (not intentionally making any expression). This phrase is typically only used to describe women. I'm not mad, I just have RBF. She looks grumpy but she just has RBF. She's actually very approachable!

The function of RBF network is Gauss basis function, and the solution of its variance can be solved as follows.
The most useful RBF with localized feature which lead to sparse symmetric positive definite matrices and a quicker interpolation process is Wendland's function [25].
However, the study variables showed no spatial dependence or it was very weak (nugget effect value close to sill value), thus, only deterministic interpolation techniques were performed which were: Inverse distance weighting (IDW), Radial basis functions (RBF) and Local Polynomial interpolation (LPI).
Preliminary investigations indicate that the RBF was present around old electricity wooden poles and plastic material thus making it highly likely to be the source of the fire, causing it to quickly expand to the nearby flammable materials.
